We're dividing 398291 by 17 
Our goal is to divide 398291 by 17.

Advancing to step 1:
When dividing 3 by 17, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 17

On to step 2:
17 goes into 39 2 times with a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 34 from 39 and we're left with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 17

Let's proceed to step 3:
When dividing 58 by 17, we get 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 51 from 58 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 17

Going ahead to step 4:
17 goes into 72 4 times with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 234.0
Subtracting 68 from 72 leaves us with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 17

Let's proceed to step 5:
When dividing 49 by 17, we get 2 with a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 2342.0
Deduct 34 from 49 and we're left with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 17

Advancing to step 6:
When dividing 151 by 17, we get 8 with a remainder of 15.
The next digit of our result is 8. 
Result so far: 23428.0
If we subtract 136 from 151, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
17 can be fit into 150 8 times, resulting in a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 23428.8
If we take 136 away from 150, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
17 can be fit into 140 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 23428.88
Deduct 136 from 140 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 23428.88, and the remainder is 0.004.
